[0003] Precision etching knife dies are the most common molds in the etching process. Through punching, the workpiece can be quickly formed. Its structure is relatively simple. It is mainly composed of three parts: a knife plate, a blade, and a raised aluminum plate on the back. The blade and knife plate are usually made of steel. There are some functional deficiencies in actual use and there is room for improvement. For example, the common etching knife dies on the market currently have an integrated molding and whole-piece structure for the knife plate and blade. During the punching process, the knife plate is prone to warping and deformation after long-term continuous work and pressure. After local warping and deformation, the entire template must be replaced. The durability is insufficient and the replacement cost is high.

The second fixing bolt 8 is screwed in along the end groove eye of the first fixing bolt 6 to form a traction on its back, reducing the probability of the first fixing bolt 6 turning loose during the punching process. According to the size specifications and padding requirements of the die-cutting machine, a padding aluminum plate 11 of corresponding size can be selected, and the padding aluminum plate 11 can be attached to the back of the steel main board 1. The limiting protrusion 9 on the back of the steel main board 1 and the limiting groove 12 at the front end of the padding aluminum plate 11 can be engaged, and the padding aluminum plate 11 is aligned. Then, the aluminum plate fixing bolts 15 are driven into the limited reserved screw eyes 13, and the aluminum plate fixing bolts 15 are screwed into the internal threaded alloy tube 10 along the limited reserved screw eyes 13 to complete the connection between the padding aluminum plate 11 and the steel main board 1. For later disassembly and replacement, you only need to loosen and pull out the aluminum plate fixing bolts 15.
